Cell organelles are specialized structures within a cell that perform specific functions. They are essential for the proper functioning of cells, and their presence and function can vary depending on the type of cell. Some examples of cell organelles include the nucleus, mitochondria, and endoplasmic reticulum.

The nucleus is a cell organelle that contains the cell's genetic material, which is made up of DNA and RNA. It is responsible for controlling the cell's activities, including growth, metabolism, and reproduction. The nucleus is separated from the rest of the cell by the nuclear envelope, which consists of two membranes. The inner membrane is continuous with the endoplasmic reticulum, while the outer membrane is connected to the cytoplasm.

The mitochondria are another important cell organelle. They are the powerhouses of the cell, producing energy in the form of ATP through the process of cellular respiration. They are found in the cytoplasm and are composed of two membranes. The inner membrane is folded into cristae, which increase the surface area for the production of ATP.

The endoplasmic reticulum (ER) is a cell organelle that is involved in the synthesis and transport of proteins and lipids. There are two types of endoplasmic reticulum: the rough endoplasmic reticulum (RER) and the smooth endoplasmic reticulum (SER). The RER is covered in ribosomes, which are responsible for the synthesis of proteins. The proteins are then transported through the RER and into the Golgi apparatus, where they are modified and sorted before being transported to their final destination. The SER, on the other hand, is involved in the synthesis of lipids and the detoxification of drugs and other harmful substances.

Other cell organelles include the Golgi apparatus, lysosomes, and peroxisomes. The Golgi apparatus is responsible for modifying, sorting, and distributing proteins and lipids within the cell. Lysosomes contain enzymes that help to break down and recycle waste materials within the cell. Peroxisomes are similar to lysosomes in that they contain enzymes, but they are primarily involved in the breakdown of fatty acids and the detoxification of harmful substances.

In conclusion, cell organelles are specialized structures within a cell that perform specific functions. They are essential for the proper functioning of cells and include the nucleus, mitochondria, and endoplasmic reticulum, among others. Understanding the role of cell organelles is crucial for understanding the overall functioning of cells and their role in the body.

All cells are covered by a cell membrane and come in different shapes; the contents of a cell are called protoplasm, this includes the substance within and the cell and it can be divided into two categories cytoplasm and the nucleus. Tissue cells form the brain, these are specialized cells called neurone or nerve cells. Chloroplast — an elongated or disc-shaped organelle containing chlorophyll. Endoplasmic reticulum Is an elaborate system of membrane bound sacs cisternae that are often continuous with the Golgi body and the nuclear envelope. Society is made up of various institutions for example education or family , Functionalists believe that these institutions rely on each other each other which helps maintain social order. Smooth endoplasmic reticulum transport materials through the cell. Some cells have more than one nucleolus.

The vacuole is filled with cell sap, a concentrated solution which acts as a storage site fro chemicals, mineral salts, dissolved gasses, wastes and pigments. The score is 7 to 6, the Karyotic Pros are winning. Chemical which are carried out inside the cell, such as respiration in the mitochondria; Excretion where Cells must get rid of excretory wastes; they usually do this by pushing waste out of the cell through the cell membrane. Other organelles Peroxisomes - protect the cell from it's own production of hydrogen peroxide which is produced by white blood cells. Please select the correct team and hour from the drop down menu under "Writing About Cells" to post a carefully thought out response. Mitochondria also helps in the building of certain parts of the blood, and hormones like testosterone and estrogen. If the protoplasm is more liquid it is called a sol, if more gelatinous, a gel.

Plant cell organelles Chloroplasts Photosynthesis takes place here. Nucleus — spherical body containing many organelles, including the nucleolus. As the ribosome builds the amino acid chain, the chain is pushed into the ER. Genetics is the main force which drives human development. The human body is made up of various different parts that function together, each part is necessary for the normal functioning of the whole body. The threat of new mutations is not focused on the chances of super powers forming, but more along the lines of damaging the overall human genome. There are two types of endoplasmic reticulum ER Rough ER rER - has ribosomes lining it and is involved in protein synthesis as a transport system Smooth ER sER - lacks ribosomes and is involved in the synthesis and transport oflipids Golgi Apparatus Is a collection of flattened membrane bound sacs that are constantly forming on one side and budding off as vesicles on the other.

This layer of cellulose fibre gives the cell most of its support and structure. This is where the digestion of cell nutrients takes place. Chlorophyll or closely-related pigments substances that colour the plant are essential to the photosynthetic process. Human development has many facets and driving forces. The nucleus is surrounded by the nuclear membrane. They can either be found free in the cytoplasm or on the outer surface of the rough endoplasmic reticulum. The main proteins in connective tissues are collagen and elastin Muscle - provides stability to skeleton and organs as well as allowing movement.

This is like a power plant because the power plant supplies electricity to the entire town. The mitochondrion converts the energy stored in glucose into ATP adenosine triphosphate for the cell. Adenosine triphosphate — is a high-energy molecule used for energy storage by organisms. This however, will have a negative impact in the long run. Centri and Ole are mainly in charge of finding good players for the team. Anyway, back to the game.

It is enclosed by a double membrane, and is identifiable due to its cristae which tend to divide their interiors. The nucleus is the main control center for the cell. But plant cells also have a cell wall, chloroplasts and vacuole. Functions of the Protoplasm Reproduction where the Cells divide to form identical cells. Connective - supports and protects. The nucleus controls many of the functions of the cell by controlling protein synthesis and contains DNA in chromosomes. Within the nucleus is a small spherical body called the nucleolus which manufactures RNA to from ribosomes.

An organ is composed of different tissues that are co-ordinated to perform a function Organs work together as a single unit or organ system Organisms are made up of a number of different systems working together. Rough ER is covered with ribosomes that give it a rough appearance. The cytoplasm is inside the nucleus and it controls the cells activities. Rough ER transports materials through the cell and produces proteins in sacks called cisternae which are sent to the Golgi body, or inserted into the cell membrane. This is the last game of the world series. After cell death they completely breakdown the cell autolysis release their enzymes outside the cell exocytosis in order to breakdown other cells. I honestly had totally forgotten about the assignment until she reminded me.

Some reactions also take place in the matrix Kreb's cycle as well as the cystol of the cytoplasm. Coach Bob Nucleus, the organelle who is in charge of the Eukaryotes, is shaking his head in the dug out. In 9th grade, I had an amazing biology teacher, Ms. Some tissues may be made up of a single type of cell whilst others have more than one type of cell included. Unlike the centrosomes in animal cells, plant cell centrosomes do not have centrioles.
